    Borderless POPUP-lightbox picture/image

    Asked by szendavi on January 28, 2016 at 09:10 AM


    I'd like to make a borderless/full frame popup window, with just one uploaded picture? What should I set up, to have mi popup lightbox window without any white,... frame and anything. JUST 1 PICTURE + a close "X" button.

    Hi David,

    You can use the following CSS code to disable the padding and margin values of the form and also, you can stretch the image's width and height values by injecting some custom CSS to your form.


    img {

    width: 100%;

    height: 100%;


    .form-line, .form-all, .jotform-form{

    padding: 0 !important;

    margin: 0 !important;



    Please, try this one and let us know the results.
